Simulated K-band images and radial surface brightness profiles of some S0-like remnants from our sample of major and minor mergers. The simulations assume D = 30 Mpc, μ_K,lim = 22 mag arcsec^-2 for S/N = 3, and a spatial resolution of 0.7′′. First two rows of panels: simulated K-band images of the final remnants for face-on and edge-on views. The horizontal arrow at the top left of each panel represents a physical length of 5 kpc. The field of view is 50 kpc ×50 kpc. We have used different logarithmic greyscales to highlight the structure of the outer discs (first row of panels) or of the central bulges (second row of panels). Third row of panels: simulated radial K-band surface brightness profiles and multicomponent decompositions performed to them. Dotted horizontal line: limiting surface brightness of the images. Dotted vertical lines: minimum and maximum radii considered in the fit. Black empty circles: data considered in the fit. Green filled circles: data excluded from the fit. Red dotted-dashed line: fitted Sérsic bulge. Blue dashed line: fitted exponential disc. Green long-dashed line: additional Sérsic component required in the fit (representing components such as ovals, bars, lenses, or embedded inner discs). Solid light green line: total profile resulting from the fit. Fourth row of panels: residuals of the fits as a function of radial location in the galaxy.
